Implements substring slicing with syntax &self[begin .. end] or &mut self[begin .. end].
Returns a slice of the given string from the byte range
[begin, end).
This operation is O(1).
Prior to 1.20.0, these indexing operations were still supported by
direct implementation of Index and IndexMut.
Panics if begin or end does not point to the starting byte offset of
a character (as defined by is_char_boundary), if begin > end, or if
end > len.
let s = "L枚we 鑰佽檸 L茅opard";
assert_eq!(&s[0 .. 1], "L");
assert_eq!(&s[1 .. 9], "枚we 鑰");
// these will panic:
// byte 2 lies within `枚`:
// &s[2 ..3];
// byte 8 lies within `鑰乣
// &s[1 .. 8];
// byte 100 is outside the string
// &s[3 .. 100];slice_index_methods)Returns a shared reference to the output at this location, if in bounds. Read more
